Illinois EPA issues MS4 non-compliance advisory; Carbon Cliff must submit stormwater plan by Aug. 27

The Village of Carbon Cliff reported it has received a Non-Compliance Advisory from the Illinois Environmental Protection Agency concerning the village’s Municipal Separate Stormwater Sewer System (MS4). The advisory requires the village to "develop, implement, and enforce a Stormwater Management Program" and to submit a written response by Wednesday, Aug. 27, 2025, that includes specific remedial actions and a timeline for each action.

The minutes do not record public discussion or a vote on the advisory; the requirement and deadline appear under "Old Business." The advisory likely obliges the village to set concrete compliance milestones; the minutes state the written response "must include specific remedial actions, including a specific time for achieving each action." The Board did not record a formal direction in the minutes beyond noting the advisory and the Aug. 27 deadline. The minutes list follow-up items elsewhere (legal outreach on related matters), and staff contact with the village attorney is noted in separate old-business items.

Next steps recorded in the minutes are administrative: the advisory must be answered in writing by the Aug. 27 deadline. The minutes do not specify which department will prepare the response, whether outside consultants will be retained, or any estimated cost for remedial work; those details were not specified in the record.
